Overview
Colony counter XK98-A is a digital display semi-automatic bacterial inspection instrument, which consists of a counter, a probe pen, a counting cell and other parts. The instrument is designed and manufactured with CMOS integrated circuit, and the black deep background counting cell is illuminated by energy-saving ring fluorescent lamps. The colony contrast is clear, which can reduce the labor intensity of the experimenter and improve the work efficiency and work mass.
Features
1. CMOS integrated circuit design and manufacture, Reliability
2. Black deep background counting cell with energy-saving ring fluorescent lamp side-shot lighting, clear colony contrast
3. Three-digit display design, in line with the requirements of bacterial count inspection procedures
4. Voice count function, easy to operate
5. Semi-automatic counting to reduce labor intensity
Principle
The instrument contacts the colonies at the bottom of the culture dish through the probe pen. Each contact with a colony will generate a sound prompt and automatically count, and the digital display will display the number of colonies in real time. When the number of colonies exceeds 300, it should be diluted according to the rules to ensure the accuracy of counting.
Applications
Bacterial inspection in food, beverages, pharmaceuticals, biological products, hygiene products, drinking water, industrial wastewater, and clinical specimens
Steps
1. Turn on the power supply and turn on the light of the counting pool.
2. Insert the Probe plug into the instrument socket and press the reset button to return the instrument to zero.
3. Put in culture dishes for testing
4. Use the probe pen to count the colonies one by one at the bottom of the culture dish, and hear the sound prompt to indicate that the count is valid
5. Carefully check the magnifying glass to make sure nothing is missing
6. Record the number of colonies on the display
7. Remove the culture dish and press the reset button to restore the screen to its original state
Notice
• The instrument should be placed on a flat and sturdy surface for use
• Do not tilt the Probe too much when counting colonies, enter the number when the probe is gently pressed until there is a bounce sensation
• The instrument should be moisture-proof, shockproof, avoid direct sunlight, acid and alkali erosion, and a dust cover should be added after use
• Take care to prevent bacteria from fostering contamination of the counting tank
• Both the instrument and the Probe cannot be disassembled at will. If any faults are found, an experienced technician should be asked to repair them
